Multiplexing interlaces with a single carrier waveform

Abstract

Aspects relate to implementing multiplexing with a single carrier waveform. In some examples, a total bandwidth may be divided into a plurality of bandwidth parts (BWPs), each including a plurality of tones. Each of the BWPs may further be divided into two or more interlaces, where each interlace includes a respective number of interleaved tones. A base station may assign each of a plurality of UEs a respective set of one or more interlaces within at least one BWP for multiplexing communication with the base station.
